Based on the calculations, the approximate value of angle θ is equal to: D. 53.1°.

How to calculate the missing angle?

From the image attached below, we can deduce that a right-angled triangle is formed with the following parameters:

  • Opposite side = 4/5.
  • Adjacent side = 3/5.

Thus, we would determine the approximate value of angle θ by using Tan trigonometric:

Tanθ = Opp/Adj

Tanθ = 4/5/3/5

Tanθ = 20/15

Tanθ = 1.3333

θ = tan⁻¹(1.3333)

θ = 53.1°.
